WILLIAM BONSLETT, OF MCHENRY,\ ILLINOIS HEAT RECLAIMER Application filed July 29, 1932. Serial No. 626,181.

Having found that all. heating plants whether steam, liot water or hot air, are low in eiiciency as compared with the inherent possibilities for maximum heating effect.

This is due mainly to the fact that all of the hot gases and products of combustion arc allowed to escape ,through the Hue connection without delivering up their full heating l values into the' home. This waste is particularly true of those heaters which are equipped with oil burners and require an increased draft, the e'ect of which is to blow l the hot gases through the iiue connection bc fore they have had an opportunity of delivering up their full heating effect.

Various heat economizei's have been dcvisedfor utilizing this waste heat passing through the iue connection, but in general these prior constructions have been expensive in design and in installation and have not been adaptable to interchanging to the different types of heating plants. Y

To avoid these objections and at the same time provide a heater that is suiiicient 1n design operation and is inexpensive'to install, I have devised my present invention.

This invention relates to a heat reclaimer, the general object of the invention being to provide means for utilizing the prod ucts of combustion from a Jfurnace 'or the like for heating fluid such as water, whereby the heat contained in the products of combustion passing to a chimney is utilized and not permitted to go to waste. i

This invention also consists iii certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

i ln describing the invention in detail, ref-.

erence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the severaly views, and in which Figure i is a side View showing the invention and its connection to a pair of chimney pipe sections leading from a side of a fur- 50 Ila/Ce.

Fig. 2 is a section online 2 2 of Fig. 1.

Fig. 3 is a section on line 3-3 of Fig. 4, this view showing the device attached to the top of a furnace.

Fig. 4 is a front view of the device.

Fig. 5 is a section on line 5-5 of Fig. 3. w

In these drawings, the numeral 1 indicates a casing which is provided with the end ineinbers 2 and the numeral 3 indicates a water jacket extending over the top and the sides of the casing as shown. An inlet pipe 4, C0 which may be thereturn pipe of a liot water heating system is connected to the jacket space on one side of the chamber adjacent tlielower end thereof and the pipe assembly 5 is connected to the opposite side of the 65 jacket adjacent the top thereof as shown at 6 and the other end of this assembly is connected to a header pipe which passes through the casing and has its opposite end closed by a cap 8. A plurality of coils 9 each has one end connected with the header pipe 7 by the coupling 10 and the other ends of these coils are connected to the upper header pipe 11 by the couplings 12. This header 11 has one end closed by a cap 13 and its other end suitably connected to the heating system.

A nipple 14 is formed in the lower part 1 of thefront end member of the casing and the nipple 15 is formed on the upper port-ion of the rear end member and a third nipple 16 depends from the 'bottom of the casing ad jacent the front end theerof. An upright baiie plate 17 is connected with the bottom of the casing and extends upwardly to a point a slight distance from the top thereof, a this baiiie plate being arranged in front of the nipple 15, and as will belseen the coils 9 are vertically arranged in the space between the front end of the casing and the baiiie plate 17.

The nipple 14 may be connected by a pipe section 18 with the side outlet of a furnace A, as shown in Fig. 1 and the nipple 15 may be connected by a pipe section 19 with the 95 chimney. The nipple 16 is then closed by a cap 20. However, if the furnace has a smoke outlet in its top as shown at A in Fig. 3 the cap 2O is removed from the nipple 16 and placed over the nipple 14 and a pipe section 100 `chimney pipe section 19. The water from the jacket enters the lower header 7 through pipe 5 and passes upwardly through the coils 9 into the upper header so that the water is thoroughly heated by the products of combustion both in the coils and in the two headers before passing from the upper header.

By projecting both ends ofthe headers from the ends of the casing and providing the caps 8 andv 13, the headers can be connected to the system in different ways, or may be connected to two radiators at same time.

Thus I have provided a simple device for utilizing the products of combustion which usually go to waste up the chimney, for heating the Water or other fluid which may be used in the regular heating systemor in an auxiliary system.

As Will be seen the return water is iirst heated in the water jacket which, of course, is heated from the sides and top of the casing and then the water from the jacket entersthe lower header 7 thru Athe pipe assembly 5 and then passes through the coils into the upper header. Thus practically, all the heat of those products of combustion passingto the chimney is utilized in heating the water.

It is thought from the foregoing descript-ion thatthe advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement 'of the several parts provided that such'changes fall within-the scope of the appended claims. p

Having thus described my invention, what I claim as new is i l. A heat reclaimer comprising a casing, means for connecting the front portion there'- of to the furnace section of a chimney pipe, means for connecting the rear portion tothe chimney section o f said pipe whereby the,. products ofA combustion from the furnace will pass through said casing, a baille in the rearv part of the casing and extending upwardly from the bottom thereof, 'header pipes pass- A ing through the casing, coils vertically arranged and having their ends connected with the header pipes, a jacket surrounding the casing, a supply pipe connected to one side of the jacket adjacent the bottom thereof, apipe connected with the opposite side of the jacket adjacent the top thereof, means for connecting the last-mentioned pipe to the inlet header and an outlet pipe connected with the outlet header. Y

2. A heat reclaimer for use on a chimney section of said pipe, coils located in the casing, said coils being contacted by the products of combustion passing through the casing, a jacket surrounding the sides and top wall of the casing, a supply pipe connected to the lower part of one side of the jacket, and means for connecting the other side/adjacent the top thereof with the inlet ends of the coils, and outlet means connected with the outlet ends of the coils.

3. A heat reclaimer of the class described comprising a casing having an inlet nipple at the lower part Vof its front end, and an outlet nipple adjacent the upper end of its rcarend, anda third nipple depending Jfrom the bottom of the casing adjacent the front end whereby the outlet nipple can be connected toa chimney and either the front nipple or the bottom nipple to afurnace outlet. a cap for closing that nipple not in use, a coil in the casing, inlet and outlet headers connected with the coils, said coils beinglocated in the path of the products of combustion passing through the casing, and an upright baiiie connected with the, bottom of the casing and spaced from the top thereof, and arranged in spaced relation' in front of the Youtlet nipple.

4. A heat. reclaimer of the class describedv comprising a4 casing having an inlet nipple at the lower part of its front end, and an outv let nipple adjacent the upper end of itsv rear end. and a third nipple depending from the bottom of the casing adjacent the front end whereby the outlet nipple can be connected to a chimney and either the front nipple or the" bottom nipple to a furnace outlet, a cap for closing that-nipple not in use, coils in the casing.inlet and outlet headers connected With the coils, said coils being'located in the path of the products of combustion passing through the casin'gg-an upright baffle connected with thel bottom ofthe casing and spaced from the top thereof. and arranged in spaced relation in front of the outlet nipple, a jacket surrounding the sides and top of the casing, means for introducingliquid intoa part of the jacket. and means for connecting another partof the jacket with the inletvheader.

In testimony whereof I afiix my signature.

WILLIAM BONSLETT.
